Looking quite promising so far. I do hope you take my suggestion of taking a SWIV style approach to level design and use QAmiga to load data on the fly without braking the display. If you're skipping 3 frames anyway that should give you enough time to load a reasonable amount of data between display refreshes, even from floppy. And I'm not sure, but you may possibly be able to multitask data loading with game logic routines if you're in QAmiga mode
